(Operating electronic devices using gestures)
FIG. 2 shows a state in which the user operates the electronic device 1 with a gesture. In FIG. 2, the electronic device 1 is supported by a stand as an example. As an alternative example, the electronic device 1 may be leaned against a wall or placed on a table. When the proximity sensor 18 detects a user gesture, the controller 11 performs processing based on the detected gesture. In the example of FIG. 2, the process based on the gesture is scrolling of the screen on which the recipe is displayed. For example, when the user performs a gesture of moving his / her hand upward in the longitudinal direction of the electronic device 1, the screen scrolls upward in conjunction with the movement of the user's hand. Further, for example, when the user performs a gesture of moving the hand downward in the longitudinal direction of the electronic device 1, the screen scrolls downward in conjunction with the movement of the user's hand.

  The electronic device 1 shown in FIG. 2 is a smartphone. As an alternative example, the electronic device 1 may be, for example, a mobile phone terminal, a Fablet, a tablet PC, or a feature phone. Further, the electronic device 1 is not limited to the above, and may be, for example, a PDA, a remote control terminal, a portable music player, a game machine, an electronic book reader, a car navigation, a home appliance, or an industrial device (FA device).

(Method for detecting gestures)
Here, a method in which the controller 11 detects a user gesture based on the output of the proximity sensor 18 will be described with reference to FIGS. 3 and 4. FIG. 3 is a diagram illustrating a configuration example of the proximity sensor 18 when the electronic apparatus 1 is viewed from the front. The proximity sensor 18 includes a light source infrared LED 180 and four infrared photodiodes SU, SR, SD, and SL. The four infrared photodiodes SU, SR, SD, and SL detect reflected light from the detection target via the lens 181. The four infrared photodiodes SU, SR, SD, and SL are arranged symmetrically when viewed from the center of the lens 181. Here, it is assumed that the virtual line D <b> 1 shown in FIG. 3 is substantially parallel to the longitudinal direction of the electronic device 1. On the virtual line D1 in FIG. 3, the infrared photodiode SU and the infrared photodiode SD are arranged apart from each other. In the direction of the imaginary line D1 in FIG. 3, the infrared photodiodes SR and SL are arranged between the infrared photodiode SU and the infrared photodiode SD.

  FIG. 4 shows the transition of the detection value when the detection objects (for example, the user's hand) of the four infrared photodiodes SU, SR, SD, and SL move along the direction of the virtual line D1 in FIG. Illustrate. Here, the infrared photodiode SU is farthest from the infrared photodiode SD in the direction of the virtual line D1. Therefore, as shown in FIG. 4, the time difference between the change (for example, increase) in the detection value (broken line) of the infrared photodiode SU and the same change (for example, increase) in the detection value (thin solid line) of the infrared photodiode SD. Is the largest. The controller 11 can determine the moving direction of the detection object by grasping the time difference of the predetermined change in the detection values of the photodiodes SU, SR, SD, and SL.

  The controller 11 acquires the detection values of the photodiodes SU, SR, SD, and SL from the proximity sensor 18. Then, the controller 11 integrates, for a predetermined time, a value obtained by subtracting the detection value of the photodiode SU from the detection value of the photodiode SD in order to grasp the movement of the detection object in the direction of the virtual line D1, for example. Also good. In the example of FIG. 4, the integral value is a non-zero value in the regions R41 and R42. From the change in the integrated value (for example, change in positive value, zero, and negative value), the controller 11 can grasp the movement of the detection target in the direction of the virtual line D1.

  Further, the controller 11 may integrate a value obtained by subtracting the detection value of the photodiode SR from the detection value of the photodiode SL in a predetermined time. From this change in integral value (for example, a change in positive value, zero, or negative value), the controller 11 moves the detection target in a direction orthogonal to the virtual line D1 (a direction substantially parallel to the short direction of the electronic device 1). Can be grasped.

  As an alternative example, the controller 11 may perform calculation using all detection values of the photodiodes SU, SR, SD, and SL. That is, the controller 11 may grasp the moving direction of the detection target without calculating the components in the longitudinal direction and the short direction of the electronic device 1.

  The detected gestures include, for example, left and right gestures, up and down gestures, diagonal gestures, gestures that draw a circle in a clockwise direction, and gestures that draw a circle in a counterclockwise direction. For example, the right and left gesture is a gesture performed in a direction substantially parallel to the short direction of the electronic device 1. The upper and lower gestures are gestures performed in a direction substantially parallel to the longitudinal direction of the electronic device 1. The oblique gesture is a gesture performed in a direction that is not parallel to either the longitudinal direction or the short direction of the electronic device 1 on a plane substantially parallel to the electronic device 1.

(Kitchen mode)
FIG. 5 shows an example of a situation where the user operates the electronic device 1 with a gesture. In the example of FIG. 5, the user is cooking according to the recipe in the kitchen while displaying the cooking recipe on the display 14 of the electronic device 1. At this time, the proximity sensor 18 detects a user's gesture. Then, the controller 11 performs processing based on the gesture detected by the proximity sensor 18. For example, the controller 11 can perform a process of scrolling the recipe according to a specific gesture (for example, a gesture in which the user moves the hand up and down). During cooking, the user's hand may become dirty or wet. However, the user can scroll the recipe without touching the electronic device 1. Therefore, it is possible to avoid the display 14 from becoming dirty and the stain of the display 14 from being transferred to the user's hand during cooking.

  Here, the electronic device 1 has a plurality of modes. The mode means an operation mode (an operation state or an operation state) that restricts the overall operation of the electronic device 1. Only one mode can be selected at a time. In the present embodiment, the mode of the electronic device 1 includes a first mode and a second mode. The first mode is a normal operation mode (normal mode) that is suitable for use in a room other than the kitchen and a place where the user is out. The second mode is an operation mode (kitchen mode) of the electronic device 1 that is optimal for cooking while displaying a recipe in the kitchen. As described above, in the second mode, it is preferable that an input operation by a gesture is possible. That is, when the mode of the electronic device 1 is switched to the second mode, it is preferable to operate the proximity sensor 18 in conjunction with the gesture so that the gesture can be detected. The electronic device 1 according to the present embodiment includes a user interface described below, and can switch the switching to the second mode (kitchen mode) and the operation of the proximity sensor 18.

(Process for determining whether gestures are valid or invalid)
Next, gesture valid / invalid determination processing by the controller 11 of the electronic device 1 will be described. The gesture valid / invalid determination process by the controller 11 may be executed when the electronic device 1 is in the kitchen mode described above, for example.

  In some cases, the user wants to continuously operate the screen displayed on the display 14 in one direction (for example, the vertical direction) in the electronic device 1. For example, the user may want to perform scrolling continuously with a continuous one-way gesture. In this case, the user can perform a continuous gesture in one direction, for example. Here, the continuous one-way gesture includes repeatedly performing the one-way gesture without stopping the hand performing the gesture, for example. The continuous scrolling includes that the screen transition by the roll on the screen is performed without stopping.

  FIG. 6 is a diagram illustrating an example of continuous gestures by the user. FIG. 6 is a diagram showing a side view of the electronic apparatus 1, and the movement of the gesture performed by the user's hand is schematically indicated by an arrow A <b> 1. FIG. 6 shows the position of the proximity sensor 18 in the electronic device 1 for explanation. As shown in FIG. 6, when performing a continuous gesture, the user draws a circle (ellipse) (or reciprocates) on the front side of the proximity sensor 18 in a side view of the electronic device 1. ) Repeatedly move the hand. At this time, the user's gesture is not detected as a motion of drawing an arc as indicated by an arrow A1, but as a gesture in a continuous opposite direction (left and right in FIG. 6), for example, as schematically illustrated as an arrow A2 and an arrow A3. May be detected. When the user's gesture is detected as a continuous gesture in the opposite direction, the controller 11 of the electronic device 1 repeatedly changes the screen displayed on the display 14 in the opposite direction (for example, the vertical direction). That is, the screen displayed on the display 14 is in a state in which, for example, upward scrolling and downward scrolling are repeatedly performed. However, since the user operates with the intention of continuous scrolling in one direction, if the electronic device 1 performs a process of repeatedly transitioning in the opposite direction on the screen, an erroneous operation occurs.

  When a plurality of gestures are continuously performed, the controller 11 of the electronic device 1 according to the present embodiment continuously performs the gesture after the first performed gesture (hereinafter also referred to as “first gesture”). The validity or invalidity of the received gesture (hereinafter also referred to as “second gesture”) is determined. The first gesture can be associated with, for example, the gesture indicated by the arrow A2 in FIG. The second gesture can be associated with, for example, the gesture indicated by the arrow A3 in FIG.

  The controller 11 determines whether the second gesture is valid or invalid based on the first gesture and the second gesture. Specifically, the controller 11 determines whether or not the second gesture satisfies a predetermined condition with respect to the first gesture, and the validity or invalidity of the second gesture is determined based on the result of the determination. To decide. When the controller 11 determines that the second gesture is valid, the controller 11 performs the process based on the second gesture after executing the process based on the first gesture. If the controller 11 determines that the second gesture is invalid, the controller 11 executes processing based on the first gesture, but does not execute processing based on the second gesture. In this way, the electronic device 1 determines whether or not the second gesture is a gesture intended by the user, and determines that the second gesture is not a gesture intended by the user. Do not perform gesture-based processing. In this way, the electronic device 1 can easily prevent an erroneous operation in an input operation using a gesture.

  Here, details of the determination condition for the validity or invalidity of the second gesture by the controller 11 and the determination process for validity or invalidity based on the determination condition will be described with some examples.

  The first determination condition is a condition regarding time. The controller 11 may determine that the second gesture is valid when the time from the first gesture to the second gesture is equal to or longer than a predetermined time. The controller 11 may determine that the second gesture is invalid if the time from the first gesture to the second gesture is less than a predetermined time.

  The time from the first gesture to the second gesture is, for example, the time from the time when the first gesture starts to be detected by the proximity sensor 18 to the time when the second gesture starts to be detected by the proximity sensor 18. It may be. The time from the first gesture to the second gesture is, for example, the time from the time when the first gesture is no longer detected by the proximity sensor 18 to the time when the second gesture starts to be detected by the proximity sensor 8. There may be.

  The predetermined time may be a time during which the user's gesture can be recognized as a continuous gesture. For example, the time from the first gesture to the second gesture is, for example, from the time when the first gesture is no longer detected by the proximity sensor 18 to the time when the second gesture starts to be detected by the proximity sensor 8. If it is time, the predetermined time may be 0.3 seconds. The predetermined time may be appropriately determined according to a function or application executed in the electronic device 1.

  For example, when a user continuously performs a one-way gesture with the intention of continuously executing scrolling, for example, the user performs a first gesture that is a gesture in an intended direction continuously. It is assumed that the first gesture is quickly returned to the position where it was started. Therefore, when the user performs a one-way gesture continuously with the intention of continuously executing scrolling, the first gesture that is a gesture in the intended direction is changed to the second that is a gesture in an unintended direction. It is assumed that the time until this gesture is shorter than a predetermined time. Therefore, when the time from the first gesture to the second gesture is less than the predetermined time, the controller 11 determines that the second gesture is an unintended gesture and invalidates the second gesture. Can be determined as Thereby, the controller 11 does not execute processing based on the second gesture determined to be an unintended gesture. In this way, the electronic device 1 can easily prevent an erroneous operation in an input operation using a gesture.

  The second condition is a condition related to the direction. If the controller 11 determines that the direction of the first gesture and the direction of the second gesture have a predetermined relationship, the controller 11 may determine that the second gesture is invalid. If the controller 11 determines that the direction of the first gesture and the direction of the second gesture are directions that do not have the predetermined relationship, the controller 11 may determine that the second gesture is invalid. .

  The predetermined relationship may be, for example, a relationship in the opposite direction. That is, in this case, the controller 11 may determine that the second gesture is invalid when it is determined that the direction of the first gesture and the direction of the second gesture are opposite directions. In this case, if the controller 11 determines that the direction of the first gesture and the direction of the second gesture are not opposite directions (for example, the same direction or a direction perpendicular to each other), the controller 11 invalidates the second gesture. May be determined.

  For example, when a user continuously performs a one-way gesture with the intention of continuously executing scrolling, the user performs the first gesture, which is a gesture in the intended direction, continuously. It is envisaged that after performing the gesture, the hand is returned to the position where the first gesture was initiated. Therefore, it is assumed that the second gesture is a gesture in the opposite direction to the first gesture. Therefore, the controller 11 determines that the second gesture is an unintended gesture when the direction of the first gesture and the direction of the second gesture have a predetermined relationship (a relationship in the opposite direction). Thus, the second gesture can be determined as invalid. Thereby, the controller 11 does not execute processing based on the second gesture determined to be an unintended gesture. In this way, the electronic device 1 can easily prevent an erroneous operation in an input operation using a gesture.

  The third condition is a condition related to distance. The controller 11 determines that the distance (first distance) between the position where the first gesture is performed and the proximity sensor 18 is the distance between the position where the second gesture is performed and the proximity sensor 18 (second distance). If so, the second gesture may be determined to be valid. The controller 11 determines that the distance (first distance) between the position where the first gesture is performed and the proximity sensor 18 is the distance between the position where the second gesture is performed and the proximity sensor 18 (second distance). If not, the second gesture may be determined to be invalid.

  In FIG. 6, the first distance is indicated by D1 as an example. The first distance may be, for example, the distance between the first gesture and the proximity sensor 18 when the first gesture is located at the closest point to the proximity sensor 18. For example, the first distance may be an average distance from the proximity sensor 18 in the first gesture.

  In FIG. 6, the second distance is indicated by D2 as an example. The second distance may be, for example, the distance between the second gesture and the proximity sensor 18 in the case where the second gesture is located at the closest point to the proximity sensor 18. For example, the second distance may be an average distance from the proximity sensor 18 in the second gesture.

  The first distance and the second distance are not limited to the above-described example, and may be determined according to any definition as long as the definitions are the same (that is, determined based on the same reference).

  For example, when the user performs a continuous gesture in one direction with the intention of continuously executing scrolling, for example, the proximity sensor 18 can easily detect the first gesture that is a gesture in the intended direction. It is assumed that the measurement is performed at a position close to the proximity sensor 18. In addition, when the user continuously performs a gesture in one direction, it is assumed that the second gesture, which is a gesture in an unintended direction, is performed at a position farther from the proximity sensor 18 than the first gesture. Is done. That is, it is assumed that the second gesture is performed at a position farther from the proximity sensor 18 than the first gesture. Therefore, when the first distance is smaller than the second distance, the controller 11 determines that the second gesture is an unintended gesture and can determine that the second gesture is invalid. Thereby, the controller 11 does not execute processing based on the second gesture determined to be an unintended gesture. In this way, the electronic device 1 can easily prevent an erroneous operation in an input operation using a gesture.

  The fourth condition is a condition related to speed. The controller 11 may determine that the second gesture is valid when the speed of the first gesture (first speed) is slower than the speed of the second gesture (second speed). The controller 11 may determine that the second gesture is invalid if the speed of the first gesture (first speed) is faster than the speed of the second gesture (second speed).

  The first speed is the speed of the gesture detected as an arrow A2 in FIG. The second speed is a gesture speed detected as an arrow A3 in FIG. The controller 11 calculates the speed of the gesture based on the gesture detected by the proximity sensor 18 and compares the first speed and the second speed.

  For example, when the user continuously performs a one-way gesture with the intention of continuously executing scrolling, for example, the user performs the first gesture, which is a gesture in the intended direction, as a gesture at a predetermined speed. Return the hand to the position where the first gesture was initiated. At this time, since the second gesture, which is an operation of returning the hand to the position where the first gesture is started, is not a gesture intended by the user, it is assumed that the operation is slower than the first gesture. Is done. That is, it is assumed that the second gesture operates slower than the first gesture. Therefore, when the first speed is higher than the second speed, the controller 11 determines that the second gesture is an unintended gesture, and can determine that the second gesture is invalid. Thereby, the controller 11 does not execute processing based on the second gesture determined to be an unintended gesture. In this way, the electronic device 1 can easily prevent an erroneous operation in an input operation using a gesture.

  The controller 11 may determine whether the second gesture is valid or invalid by combining any of the first to fourth conditions described above. That is, the controller 11 determines the time from the first gesture to the second gesture, the direction between the first gesture and the second gesture, the distance between the position where the first gesture is performed and the proximity sensor 18, and the first gesture. The second gesture based on any two or more conditions of the distance between the position where the second gesture is performed and the proximity sensor 18 and the speed condition between the first gesture and the second gesture. The validity or invalidity may be determined.

  At this time, the controller 11 may determine the validity or invalidity of the second gesture by weighting each condition for determining the validity or invalidity of the gesture according to the condition. For example, if the user continuously makes a one-way gesture, after the first gesture it is necessary to return the hand to the position where the first gesture was initiated, so the second gesture is the first gesture The direction of the gesture and the second gesture is likely to be opposite. That is, the condition regarding the direction of the gesture described as the second condition is easily satisfied. On the other hand, for example, the relationship between the distance between the gesture and the proximity sensor 18 described in the third condition may not always be satisfied depending on the user. For example, depending on the user, the first distance may be equal to or greater than the second distance even when gestures are continuously performed in one direction. That is, the condition related to the distance relationship described as the third condition is less likely to be satisfied than the condition related to the gesture direction described as the second condition. In this case, the controller 11 may perform weighting so that, for example, the second condition is scored higher than the third condition. As described above, the controller 11 may appropriately perform weighting according to the content of the condition used to determine whether the second gesture is valid or invalid. By performing the weighting, the controller 11 can more easily determine whether or not the second gesture is a gesture intended by the subject.

  FIG. 7 is a flowchart illustrating an example of processing executed by the electronic device 1.

  First, the controller 11 of the electronic device 1 detects the first gesture based on the output of the proximity sensor 18 (step S1).

  The controller 11 executes processing based on the first gesture detected in step S1 (step S2).

  The controller 11 detects the second gesture based on the output of the proximity sensor 18 (step S3).

  The controller 11 determines whether or not the second gesture is valid (step S4). Specifically, the controller 11 may determine whether the second gesture is valid by using the above-described conditions.

  If the controller 11 determines that the second gesture is valid (Yes in step S4), the controller 11 executes a process based on the second gesture (step S5). And the controller 11 complete | finishes this flow.

  When it is determined that the second gesture is invalid (No in step S4), the controller 11 determines that the second gesture is a gesture not intended by the user, and executes processing based on the second gesture. This flow is finished.

  As described above, the electronic apparatus 1 according to the present embodiment determines whether the second gesture is valid or invalid based on the first gesture and the second gesture. As a result, the electronic device 1 determines whether or not the second gesture is a gesture intended by the user, and determines that the second gesture is not a gesture intended by the user. Processing is performed so as not to execute processing based on it. In this way, the electronic device 1 can easily prevent an erroneous operation in an input operation using a gesture.

(Other embodiments)
Although the present invention has been described based on the drawings and embodiments, it should be noted that those skilled in the art can easily make various variations and modifications based on the present disclosure. Therefore, it should be noted that these variations and modifications are included in the scope of the present invention. For example, functions included in each means or each step can be rearranged so as not to be logically contradictory, and a plurality of means or steps can be combined into one or divided. .

  In the above embodiment, it has been described that the gesture is detected by the proximity sensor 18, but the gesture may not necessarily be detected by the proximity sensor 18. The gesture may be detected by any non-contact sensor that can detect the user's gesture without any contact. An example of the non-contact sensor includes, for example, the camera 13 or the illuminance sensor 20.

  In addition, the condition for determining whether the second gesture is valid or invalid described in the above-described embodiment can be appropriately set according to the content of the gesture to be determined to be invalid. For example, in the above-described embodiment, for the second condition, the controller 11 determines that the second gesture is invalid when the direction of the first gesture and the direction of the second gesture are opposite directions. Then explained. However, the second condition is that the controller 11 determines that the second gesture is invalid when the direction of the first gesture and the direction of the second gesture are the same direction. There may be.

  For example, as shown in FIG. 8, it is assumed that the user performs a gesture with a finger interval. In this case, the controller 11 can detect the gestures of the user's little finger, ring finger, middle finger, forefinger, and thumb as different gestures based on the output of the proximity sensor 18, and can detect five gestures corresponding to each finger. There is sex. However, in reality, it is assumed that the user intends one gesture by moving his / her hand from the bottom to the top. In this case, if the controller 11 detects the user's gesture as five gestures, it may cause an erroneous operation.

  However, the second condition is a condition that the controller 11 determines that the second gesture is invalid when the direction of the first gesture and the direction of the second gesture are the same direction. By doing so, the gestures of the five fingers in the same direction are not determined to be different gestures. Thereby, it becomes easy to prevent an erroneous operation.
